ing. Each pendant to be — in length, (provided with a cord adjuster) and protected by a double-pole ceiling cut-out. Both at the cut-out and in the socket the cord shall be knotted so that in no case will the weight come on the binding screws. Where the cord passes through

the neck of the socket it shall be protect

ed by a = bushing. In each socket the proper lamp shall be placed and all shades shall be attached.

Three-Wire System.

This specification is identical with the two-wire specification, except in “System,” p. 94, sec. 84, in place of which inSert the following:

All! Hors |and mains shall be fig

ured on the basis of the three-wire system, but the distribution circuits shall consist of two wires only except to outlets for a group of —, - c. p., lamps , or more, and for special circuits specifically mentioned. Care shall be taken in arranging the distribution circuits to have the same number of lamps on each side of the system and that no circuit shall be connected across the outside wires. The neutral wire shall in all cases be properly tagged and shall be run between the outside wires.

Three-Wire System Adapted to the Two-
Wire System.

This specification is identical with the two-wire specification, except in “System,” p. 94, Sec. 84, in place of which insert the following:

feeders of three wires, but the neutral wire shall consist of two wires each equal in cross-section to the outside wires, or of one wire equal in cross-section to the outside wires combined, in order that if desired all lights may be operated on the two-wire system; if two neutral wires are run they shall be permanently connected at each cut-out box. All distribution circuits shall consist of two wires only except to outlets for a group of —, c. p., lamps or more, and for special circuits specifically mentioned. In all three

All! risers, |and mains shall consist wire distribution circuits the neutral shall be equal in cross-section to the two out

side wires combined. Care shall be taken

in arranging the distribution circuits to have the same number of lamps on each side of the system and that no circuit shall be connected across the outside wires or between the neutral wires. The neutral shall in all cases be properly tagged and shall be run between the outside wires.
